Description

Envirostat FP6E | 6kW Frost Protection Thermostat | IP65

The Envirostat FP6E is a robust electronic frost-protection thermostat with alarm indication and temperature-control functions, designed to provide reliable, energy-efficient protection for pipework, tanks, and exposed equipment where insulation alone cannot prevent freezing. Suitable for controlling heater tapes and infrared (IR) quartz lamps, the FP6E automatically activates heating when temperatures fall below the selected set point, helping to prevent costly frost damage.

Featuring a built-in 2m encapsulated temperature sensor, soft-start switching, and an IP65-rated enclosure, the FP6E is built for dependable operation in demanding industrial and commercial environments. Its maintenance-free solid-state design delivers long-term reliability while minimising energy consumption by only operating heating when required.

Designed for quick installation and straightforward operation, the Envirostat FP6E is an ideal solution for frost protection applications across industrial, commercial, and outdoor installations.
